Katundu, Ubwino ndi Kugwiritsa Ntchito Ductile Iron

Chitsulo chopangidwa ndi ductile, chomwe chimadziwikanso kuti chitsulo chopangidwa ndi spheroidal kapena nodular, ndi gulu la zitsulo zopangidwa ndi chitsulo zokhala ndi kapangidwe kake kapadera komwe kamawapatsa mphamvu zambiri, kusinthasintha, kulimba, komanso kusinthasintha. Chili ndi mpweya woposa 3 peresenti ndipo chimatha kupindika, kupindika, kapena kusokonekera popanda kusweka, chifukwa cha kapangidwe kake ka graphite flake. Chitsulo chopangidwa ndi ductile chimafanana ndi chitsulo m'makani ake ndipo chimakhala cholimba kwambiri kuposa chitsulo chopangidwa ndi chitsulo wamba.

Kuyika zitsulo zopangidwa ndi ductile iron kumachitika pothira zitsulo zopangidwa ndi ductile mu nkhungu, pomwe chitsulocho chimazizira ndikulimba kuti chipange mawonekedwe omwe mukufuna. Njira yopangira izi imapangitsa kuti zinthu zolimba zikhale zolimba komanso zolimba.

Kodi N’chiyani Chimapangitsa Ductile Iron Kukhala Yapadera?

Chitsulo chopangidwa ndi ductile chinapangidwa mu 1943 ngati njira yamakono yosinthira chitsulo chopangidwa ndi pulasitiki. Mosiyana ndi chitsulo chopangidwa ndi pulasitiki, komwe graphite imawoneka ngati zingwe, chitsulo chopangidwa ndi ductile chili ndi graphite mu mawonekedwe a spheroids, motero mawu akuti "spheroidal graphite." Kapangidwe kameneka kamalola chitsulo chopangidwa ndi ductile kupirira kupindika ndi kugwedezeka popanda kusweka, zomwe zimapereka mphamvu zambiri kuposa chitsulo chopangidwa ndi pulasitiki, chomwe chimakonda kusweka ndi kusweka.

Chitsulo chopangidwa ndi ductile chimapangidwa makamaka ndi chitsulo cha nkhumba, chitsulo choyera kwambiri chokhala ndi chitsulo choposa 90%. Chitsulo cha nkhumba chimakondedwa chifukwa chili ndi zinthu zochepa zotsalira kapena zovulaza, mankhwala ogwirizana, komanso chimalimbikitsa mikhalidwe yabwino kwambiri yotsalira panthawi yopanga. Zinthu zoyambira izi ndi chifukwa chachikulu chomwe opanga zitsulo zopangidwa ndi ductile amakonda chitsulo cha nkhumba kuposa zinthu zina monga chitsulo chotsalira.

Katundu wa Ductile Iron

Mitundu yosiyanasiyana ya chitsulo chosungunuka imapangidwa mwa kusintha kapangidwe ka matrix kuzungulira graphite panthawi yopangira kapena kudzera mu chithandizo china chowonjezera cha kutentha. Mitundu yaying'ono iyi ya kapangidwe kake imapangidwa kuti ikwaniritse kapangidwe kakang'ono, komwe kumatsimikiza mawonekedwe a chitsulo chosungunuka chilichonse.

Chitsulo chopangidwa ndi ductile chingaganizidwe ngati chitsulo chokhala ndi ma graphite spheroids ophatikizidwa. Makhalidwe a matrix achitsulo ozungulira ma graphite spheroids amakhudza kwambiri mawonekedwe a ductile iron, pomwe graphite yokha imathandizira kuti ikhale yolimba komanso yosinthasintha.

Pali mitundu ingapo ya matrix mu ductile iron, ndipo yodziwika kwambiri ndi iyi:

1. 1. Ferrite– Chitsulo choyera chomwe chimapindika mosavuta komanso chosinthasintha, koma chili ndi mphamvu zochepa. Ferrite ili ndi mphamvu zochepa zotha kusweka, koma kukana kwake kwakukulu komanso kosavuta kugwiritsa ntchito kumapangitsa kuti ikhale chinthu chofunikira kwambiri pakupanga chitsulo chopindika.
2. 2. Pearlite– Chopangidwa ndi ferrite ndi iron carbide (Fe3C). Ndi cholimba kwambiri ndipo chimakhala cholimba pang'ono, chimapereka mphamvu zambiri, chimatha kusweka bwino, komanso chimatha kugwedezeka pang'ono. Pearlite imaperekanso makina abwino.
3. 3. Pearlite/Ferrite- Kapangidwe kosakanikirana ndi pearlite ndi ferrite, komwe ndi matrix yodziwika bwino kwambiri m'magawo amalonda a chitsulo chosungunuka. Chimaphatikiza makhalidwe a zonse ziwiri, kupereka njira yoyenera ya mphamvu, kusinthasintha, ndi kuthekera kwa makina.

Kapangidwe kake kapadera ka chitsulo chilichonse kamasintha mawonekedwe ake:

Magiredi a Iron Omwe Amagwiritsidwa Ntchito Pamodzi

Ngakhale pali mitundu yosiyanasiyana ya chitsulo chopangidwa ndi ductile, mafakitale opangidwa ndi chitsulo nthawi zambiri amapereka mitundu itatu yofanana:

Ubwino wa Ductile Iron

Chitsulo cha ductile chili ndi ubwino wambiri kwa opanga ndi opanga:

• • Itha kupangidwa mosavuta komanso kupangidwa ndi makina, zomwe zimachepetsa ndalama zopangira.
• • Ili ndi chiŵerengero champhamvu kwambiri pakati pa kulemera, zomwe zimathandiza kuti ikhale yolimba koma yopepuka.
• • Chitsulo chopangidwa ndi ductile chimapereka kulimba bwino, kugwiritsa ntchito bwino ndalama, komanso kudalirika.
• • Kulimba kwake kwambiri komanso kuthekera kwake kogwiritsa ntchito makina kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zovuta.

Kugwiritsa Ntchito Ductile Iron

Chifukwa cha mphamvu zake komanso kulimba kwake, chitsulo chopangidwa ndi ductile chimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Chimagwiritsidwa ntchito kwambiri m'mapaipi, zida zamagalimoto, magiya, ma pompu, ndi maziko a makina. Kukana kwa chitsulo chopangidwa ndi ductile kumapangitsa kuti chikhale choyenera kugwiritsidwa ntchito pachitetezo, monga ma bollards ndi chitetezo cha kugunda. Chimagwiritsidwanso ntchito kwambiri m'makampani opanga mphamvu zamphepo ndi malo ena opsinjika kwambiri komwe kulimba ndi kusinthasintha ndikofunikira.
